Add the flour listed in the topping portion of the recipe with the rest of the ingredients in step 6.
I'm not sure the filling needs any flour, but Liz may have used some to thicken it a bit. I probably would add no more than a tablespoon.

Thanks HLA: I took an educated guess & did exactly that. (Initially began adding flour to the pears & hurriedly scrambled to remove most of it with a spoon. Net result: the pears did get coated with some flour.. Its sitting in the oven now & smells YUM!)
I also went ahead & added the ginger to the pears (there is no explicit instruction in the recipe for where the crystallized ginger is supposed to go..)

Yikes - I will have to look at my recipe. I wanted a T. or so of flour to coat the pears - and the ginger to go with the pears as well, along with the vanilla, lemon juice and zest and some brown sugar. I'm so sorry for the confusion. I actually came here to ask a question of my own about something else!
